The tree in our driveway has a tiny green bud containing a new leaf. Despite the cold this week, I declare spring.
False Bay is quite surgy after some large swell this week, but I hope it’ll have settled down enough by Sunday for some reasonable diving. I’ll only make the call on Saturday afternoon; please let me know if you’d like to be notified of any developing plans.

Beach cleanups
There are at least two happening this weekend:
The regular new moon beach cleanup at Surfers Corner, Muizenberg beach, organised by The Beach Co-Op (info on facebook) on Saturday at 9am
There’s a fascinating update this week from Shark Spotters on False Bay’s white sharks (spoiler: they’re awol but we’re not quite certain why yet) – read more here.
I had to write a short article about Shark Spotters a while ago, for the quarterly magazine of the company I work for. It was fun to write within the constraints of quite a punitive word count, and to try and emphasise the aspects of the program that I think are poorly understood by the public. Here’s the article:
Shark Spotters developed into Cape Town’s primary shark safety strategy out of two similar, informal initiatives. At Muizenberg and Fish Hoek in 2004, surfers arranged with lifeguards, car guards and trek fishermen to warn them when sharks were sighted. Today, Shark Spotters is a NPO funded primarily by the City of Cape Town, Save Our Seas Foundation, and public donations. It operates year-round at four beaches and during summer at another four. These are beaches that have both many water users and relatively common shark sightings.
A team of 30 spotters equipped with binoculars, polarising sunglasses and all-weather gear watch from the mountainside, and when a shark is sighted they notify colleagues at the beach to sound a siren and raise the appropriate flag. The flags indicate the current or recent presence of a shark, that spotting conditions are poor, or that it is safe to swim.
The spotters, all drawn from local communities, are trained in safety, first aid and shark behaviour. A further 10 team members deploy and retrieve the shark exclusion net at Fish Hoek beach during summer. Unlike the gill nets protecting beaches in KwaZulu Natal, this net does not catch sharks. It provides a physical barrier between sharks and swimmers. It is designed to be retrieved at the end of the day, or, to prevent entanglement, when there are marine mammals nearby. The Fish Hoek shark exclusion net is unique worldwide as an environmentally friendly shark attack mitigation measure.
It is the combination of favourable topography and surface-swimming sharks that makes Shark Spotters’ work possible and effective. The land around many of Cape Town’s beaches slopes steeply towards the sea, providing raised vantage points from which to spot. The sharks which pose the primary danger to water users, because of their size and curious natures, are great white sharks. Fortunately these sharks spend much time swimming on the surface, and their distinctive swimming style is readily recognisable.
Shark Spotters also conducts research on sharks to improve safety measures and provide management and conservation recommendations. As a result, the movements of great white sharks in False Bay are well understood. Sharks visit the beaches year-round, but with a distinct seasonal pattern. During winter the sharks congregate at Seal Island to feed on juvenile seals. During summer, sharks head for the backline of Cape Town’s beaches – probably to feed on the fish species found in False Bay at this time, and to rest in the highly oxygenated water close to shore. This is when they pose the greatest risk to water users.
Why support Shark Spotters?
I love the fact that Shark Spotters combines care for people with concern for the environment. The program takes a scientific stance backed by research, and has attracted worldwide recognition. It also provides training and employment for 40 residents of some of Cape Town’s most impoverished communities. I sit on the non-executive committee as a representative of Cape Town’s scuba diving community, and it’s a privilege to work with fellow water users and ocean lovers, and hopefully to provide a benefit to the greater community through our small contribution.
(Of course, lately white shark movements in False Bay are slightly less well understood than they have been, probably thanks to a pair of orcas whose irregular visits to Seal Island and Millers Point to hunt white sharks and sevengills seem to clear out the neighbourhood a bit! Fear not, Shark Spotters’ research is aiming to understand these changes, too.)
We are proud to announce that we have signed on as official supporters of Shark Spotters. We are Silver partners, and for larger businesses there are higher levels of support on offer. (We are hoping to encourage some of the other dive centres to consider supporting Shark Spotters, too…) Individuals can also sign on to the supporters program, or donate in many different ways. Shark Spotters is part-funded by the City of Cape Town and the Save Our Seas Foundation, and the rest comes from public donations.

The shark exclusion net has been around for about five years, and (unlike the gill nets in KZN) is specially designed not to pose a hazard to any marine life. It gets taken in every evening, to eliminate the risk of an animal becoming entangled at night when the spotters are not on duty. It is an extremely successful and popular feature of Fish Hoek beach, and is invariably packed with happy, safe swimmers during the summer months. If you’re curious about it, watch the video above to see what it looks like from underwater, and read more about it here, here and here.
The Shark Spotters info centre at Muizenberg
Their research continues to illuminate the activities of white sharks in the bay, but is also in the process of shedding light on the interactions between white sharks, sevengill cowsharks and bronze whalers as they share the ecosystem. They have even published a recent paper (open access) on the predation of sevengill cowsharks by orcas in False Bay, which is well worth a read.
The Shark Spotters outpost at Caves (Kogel Bay)
Currently, they’re partnering with a Swiss firm in a cutting-edge research project to determine how automated shark spotting, making use of cameras and machine learning algorithms, can augment the already impressive skills of the spotting team. By first training a sophisticated algorithm to distinguish between a shark, pieces of kelp, dolphins, wind chop, and all the other visual phenomena that a spotter comes across during the course of a day, it is hoped that a fixed camera system, with some software, could assist the spotters in their work. It is not intended to replace human spotters, but to augment and facilitate their work.

We’re happy to be contributing to the important work of Shark Spotters – if you’d like to as well, visit their website to find out how to lend your support, or drop me an email and I’ll connect you with the right people.
The weather forecast predicts that we are soon to be lashed with 50 km/h winds, a 7 metre swell, and no small amount of rain. It seldom is as bad as the forecasts claim, however the swell size and direction will hammer False Bay. Despite Sunday’s weather looking peachy, I don’t think the ocean will be, so we will plan for a dry weekend… It is winter after all.

Shark Spotters supporters program
We are proud to announce that we have signed on as official supporters of Shark Spotters. We are Silver partners, and for larger businesses there are higher levels of support on offer. (We are hoping to encourage some of the other dive centres to consider supporting Shark Spotters, too…) Individuals can also sign on to the supporters program, or donate in many different ways.
We’ll write a blog post with more information soon – but in the mean time, we’re very happy to be contributing to the important work of Shark Spotters. If you’d like to as well, visit their website to find out how to lend your support, or drop me an email and I’ll connect you with the right people.
Neither day of the weekend looks all that promising for diving. The Atlantic is most likely to have the better visibility, however the swell on Friday and early on Saturday is not really my cup of tea. I will take a look at False Bay on Saturday, and possibly launch there on Sunday if it looks decent. If you’d like to dive, let me know!

Turtle time!
We are entering into the busiest time for turtle wash-ups on the Western Cape coastline. On Tuesday, 14 (yes, fourteen) baby turtles stranded themselves in Hermanus. These little animals are in a highly compromised state when they end up on the shore, as they can’t cope with the cold waters this far south.
The Two Oceans Aquarium has a sophisticated turtle rehab facility, and, once they’re fattened up and restored to full health, the little turtles are released in the summer months when the warm current is closest to the Cape Peninsula coastline. Read about what to do if you find a baby turtle here. Local drop off points for tiny turtle guests are at the Two Oceans Aquarium (obvs), and the Shark Spotters info centre in Muizenberg.
After a successful Back a Buddy campaign, Shark Spotters launched their free shark safety smartphone app in the summer of 2016. The app has had excellent uptake by water users of all stripes, but I’d like to draw it to your attention in case you aren’t familiar with the ways in which it can make your beach life better and safer! Whether you’re a surfer, a diver, an ocean swimmer, a beach comber, or someone who looks forward to long summer days under an umbrella on the sand, the Shark Spotters app can make a difference to you.
The list of Shark Spotters beaches
Shark Spotters operate at eight beaches around the Cape Peninsula: four (Muizenberg, St James/Kalk Bay, Fish Hoek & Caves, Kogel Bay) year-round, and another four (Glencairn, Clovelly, Monwabisi and the Hoek, Noordhoek) from October to April, during the warmer months.
The app allows one to set a home beach – you can see from the image above that mine is Fish Hoek – and when you start the app, you’ll get information for your home beach immediately. Tapping on the home beach block at the top of the screen (where it says “Tap for more”) brings one to a series of screens that you can navigate through by swiping the bottom block on the screen.

Shark sightings history
The information provided is extensive. You can see information on the last three shark sightings at your home beach, the weather and sea conditions (temperature, wind direction, tides, moon phase, swell), and information on what marine life is in the area. This latter information is not a nice to have so you can look out for dolphins from shore, but an important indicator of the likelihood of a shark being in the area. Dolphins, rays and schools of fish can draw white sharks, while sunfish (and even seals) may be mistaken for a shark when viewed from a distance by an untrained observer.
There’s also information on what facilities are available at the beach, and a short video for each beach, usually taken each morning, showing the prevailing conditions.
All this information is available for all the Shark Spotters beaches, not just your home beach, and you can view a different beach by selecting it from the list that appears under your home beach on the home screen.
Digging into the app, you can find a detailed list of all the recorded shark sightings, and in the settings you can turn notifications of sightings on or off according to your preference. I have them switched on, because I like to be reminded of a world outside the office.
Shark Spotters app menu options
The further menu options, shown above, give you access to a large amount of data about the Shark Spotters program, the exclusion net at Fish Hoek beach, how the flag system works, great white sharks, and more. Most of the menu options also provide links to more detailed information online, if you want to know more.
Chaps, Festivus (for those of you who find tinsel distracting) is around the corner. This year, as a principle, the gifts that I’m giving to the people I care about are skewed towards experiences, and when they are things, I’m trying to make them beautiful things that will enable my chums to live more sustainable lives.
Before I get going, however, can I point you to this excellent, far more comprehensive, far more inspired gifting guide over at twyg? Their first suggestion is “don’t gift at all”, and this is probably something well worth considering, if it won’t cause a domestic diplomatic incident.

Here’s a quick list of ideas in case you’re struggling.
An experience
A dive course or boat dive with Tony, a family photo shoot, a day out at Cape Point or up Table Mountain in the cable car, a digital magazine or streaming television subscription – use your imagination!
Something water wise
It’s likely that most of us will never, in good conscience, be able to resume watering our gardens the way we used to. For this reason, water wise plants are high on my list of excellent gifts for keen gardeners. For ideas of what plants to choose, your local nursery will help, or you and the avid coastal gardener in your life can consult this excellent book.
Something to minimise waste
A set of stainless steel or glass straws (Sustainable.co.za is one stockist), glass or copper straws (check out EbonyMoon for these), or a pack of paper or other biodegradeable straws to keep at home and/or carry around like a dork for use at restaurants.
A reusable coffee cup – Seattle Coffee Company sells beautiful Keep Cups, as do Vida e Caffe and many supermarkets. ecoffee cup sells beautiful bamboo cups, with a range of designs to choose from.
A reusable shopping bag – most supermarkets stock bags of some description, as does Faithful to Nature. 3friends has beautiful Shweshwe printed bags that are very special. We should all have a reusable shopping bag in our handbags, as well as several in the car.
A bokashi bin, which you can find at Builders Warehouse or at many nurseries. Don’t be grossed out – we have significantly improved the soil quality in our garden, and don’t put out any food waste or scraps with our garbage any more, thanks to diligent use of this nifty indoor composter!
Something to lift up someone else
Some deserving, marine-related recipients of a donation on your friend’s behalf are:
There are many more excellent non profits than just these three, and so much need, but do your research carefully. My rule of thumb is, if the founder’s face is plastered everywhere and it looks more like a personality cult than an NPO, it’s not a cause that I want to give my bucks to.
A donation of time is a way to do something great, and spend time with someone you care about. Promising to join a friend for a beach cleanup followed by a coffee (in your reusable cup, your treat) gives a gift to the planet, and the gift of time to someone you value. To find a local clean up, follow the Beach Co-Op (facebook) and Cape Town Beach Clean Up (facebook). The Two Oceans Aquarium also arranges periodic beach cleans. (Non-Capetonians, facebook and google search are your friend.)
Looking back
Previous years’ gift guides, which contain some good ideas – if I say so myself:
2017 – for info on Wild Cards or My Green Cards, small specific gifts for divers and water people
Neither the wind strength and direction, or the swell size, period and direction translate into anything close to great diving conditions. I won’t be diving but you may get lucky with some visibility in the cold Atlantic.

Reminders
I mentioned these last week, but here we go again:
Odds are that Hout Bay as well as False Bay will offer some decent diving on Saturday. I was out on the boat on Tuesday and Wednesday in False Bay and it was decent.
Hout Bay today was very green. A forecast of howling south easter for tomorrow may clean things up, but I think its best I decide where to go on Saturday after a look tomorrow afternoon. Let me know if you’re keen to dive.

Diversnight
Diversnight is on 3 November. It’s a night dive with a difference – learn all about it here. We’ll probably be at Long Beach this year to avoid the tricky conditions at the jetty at low tide (squelch!)x – here’s a facebook event to remind you of the date, and where you can post any questions you might have.
Shark Spotters / Little Optimist fundraiser
Monwabisi Sikweyiya, the original Shark Spotter and real-life hero, is participating in a race with a difference, having just learned to sail. He’ll be racing an tiny sailing dinghy against a host of other luminaries at the V&A Waterfront on 20 October. Sponsorships of Monwa will be split between Shark Spotters, who keep False Bay’s sharks and people safe, and The Little Optimist Trust, which assists ill and needy children to survive and thrive. Both very worthy causes! Donate here if you’re keen to lend a hand.
We are headed to the Tankwa Karoo for some star (and moon) gazing this weekend, so I won’t be launching. Will see you all next week!
Shark Spotters app
The Shark Spotters mobile app has been nominated for an award for best use of tech by an NGO, and your help with voting would be much appreciated by the team. Go here to vote. It’s a lot of multiple choice votes but five minutes of your time would mean a lot! You can find links to download the very useful Shark Spotters app here.
